yesterday i get this message i have contact adsense support but no answer read the message i do have a business site legal
It seems that Google Adwords have found something wrong with your site. You might have adult contents, wrong clicks, self clicked, used an automated software to click, more than few clicks from same IP etc. etc.
Normally it can take one week or so to get a reply from them. They will reinstate on cases like fake clicks etc, if you assure and give proof that it is not done by you. But in this case, it seems they are not happy with the quality / nature of your site which is difficult to get reinstated. You can at best request them to not close your account, just ban your current site. Anyway, be polite and reasonable when you contact them. And be patient. BTW, what is the nature of your site? Before sending reinstatement request, it is important to know why they banned you and assure that you will take necessary steps to improve.
lots of posts on this. Good luck getting a response from google. They usually don't tell you why and you are sol usually from what I read. Search these forums and you will find tons of people in the same boat, and google never tells them what they did or how they might resolve it.
